I should mention that Ivar the Boneless got his sweet nickname because he had a degenerative disease that left him unable to stand, and not because he needed to talk to his doctor about Cialis or anything like that. However, as a badass medieval sea-raiding shitwrecker, Ivar wasn’t going to let a little thing like “not being able to use his legs” stop him from raining death on his enemies at every turn.
In this manner, Ivar killed two kings and captured a large part of the British Isles. Link
